ELECTRIC WATER PURIFIER.

Application filed May 21,

My invention relates to electrical water purifiers including twoelectrodes adapted to ie'immersed in water to be purified by an electriccurrent passing from one electrode to the other, and my object is toprovide an efiicient device of this character which can be manufacturedat small cost and readily assembled or taken apart when it is desired tocleanse the several parts.

In order that the invention may be fully understood, reference will nowbe had to the accompanying drawing, in which:

Fig. 1 is an elevation of the device inserted in a for holding water tobe purified. V

Fig. 2 is a vertical central section of the device.

Fig. 3 is a cross section on line 3-3 o Fig. 2.

Fig. 4 is a cross section on line 44 of Fig. 2. I

Fig. 5 is a detail of an insulator having a conductor mounted thereon.

Referring in detail to the different parts, A designates a containerwhich may be of any suitable shape and size and is adapted to hold waterto be purified.

2 designates the handle of the device. Said handle 2 is made of suitableinsulating material and has an axial opening which is reduced at itsupper portion 4 and enlarged at its lower portion 6. v

8 designates an inner electrode which is preferably of rectangular crosssection throughout the greater portion of its length and is circular atits upper portion 10 which fits snugly within the enlarged portion 6 ofthe axial opening in the handle 2, where it is secured by suitable meanssuch as a screw 12 placed through a hole 14 in the side of said handle2.

16 designates a circular insulator which fits over the circular upperportion 10 of the inner electrode 8 and is clamped between the lower endof the handle 2 and the shoulder 18 formed at the juncture of therectangular and circular portions of said inner electrode 8. Theinsulator 16 has a peripheral groove in which asegmental conductor 20snugly fits and is secured at its ends by screws 22 and 24, to thelatter of which a wire conductor 26 is fastened.

The wire conductor 26 extends from any suitable source of electricity,not shown, to the screw 24 through the axial opening in the handle 2, aneccentric opening 28 in the cir-' 1927. Serial No. 193,324;

cular portion 10 of the electrode 8, and a lat cral opening 30 in thecircular insulator 16. Another wire conductor 32 extends through theaxial opening in thehandle 2 and is se cured to the upper end of theelectrode 8 by suitable means such as a screw 34. By arranging theopening 28 eecentrically as stated, sufficient metal is left at one sideof said opening for thereception of the screws 12 and'34 withoutsoldering or otherwise securing reinforcements to the circular portion10 of the electrode.

The segmental conductor 20 fits frictiontight within a tubular outerelectrode 36 which is firmly clamped against the lower end of the handle2 by means of a cap nut 38 consisting' of insulating material andthreaded upon the reduced lower end 39ofthe inner electrode 8. In orderto prevent the inner electrode 8 from rotating with the cap nut 38 whilethe latter is being screwed upon the former, I provide the circularinsulator 16 with a pair of studs41 which engage two sides of therectangular portion of said inner electrode 8 as shown by Fig. 3. Theouter electrode 86 has longitudinal slots or openings so that water maypass through to the inner electrode 8. i

In order to guard against the user of the device from becoming shockedby touching the outer electrode 36 while they electric current is on,said electrode 36 is enclosed in a housing 42 of suitable insulatingmaterial which is clamped between the handle 2 and thecap nut 38. Thehousing 42 has longitudinal slots 44 for the free circulation of waterto the electrodes 8 and 36. i v

46 designates a cover secured to the handle 2 and adapted to rest uponthe upper end of the container A and suppopt the device.

In practice when the electrodes 8 and 36 are immersed in water to bepurified A. C. or D. C. current flowing from one electrode to the othercauses precipitation of the impuri-' ties within a comparatively shorttime after the current has been turned on. Should any impurities becomedeposited upon the elec trodes access can be readily had thereto byremoving the cap nut 38, which operation permits removal of the housing42 and the outer electrode 36.

In referring to Fig. 2 it will be noted that the wire conductors 26 and32 are enclosed within and fully protected by the handle 2,

, the inner electrode 8 and the circular insulator 16, so thatwatercannot reach said Wire conductors and cause a short circuit.

Havmg thus described my invention, What I claim and desire to secure byLetters Patent,

1. A device of the character described consisting of aninner electrodeadapted to be immersed in Water Within a container, an outer electrodesurrounding said inner electrode and adapted to be immersed in thewater, a handle secured to the inner electrode and abutting one end ofsaid outer electrode, a cover for the container secured to said handle,a cap nut threaded upon the inner electrode and adapted to force theinner electrode firmlyagainst said handle, and an in sulating housingadapted to be forced by said cap nut against the handle.

2. A device ofthe character described consisting of an inner electrodewhich is circular at its upper portion and rectangular at its lowerportion, an outer electrode surrounding said inner electrode, a handlesecured to the circular portion of the inner electrode and abutting oneend of said'outer electrode, a circularinsulator fitting upon thecircular portion of the inner electrode and abutting said handle, aconductor mounted upon said insulator and fitting snugly Within theouter electrode, a cap nut threaded upon the inner electrode and adaptedto force the outer electrode firmly against said handle, and studsprojecting from the insulator and engaging two sides of the rectangularportion of the inner electrode to prevent the latter from rotating withsaid cap nut.

3. A device of the character described consisting of an inner electrodehaving a longitudinal eccentric opening at one end for the passage of aWire conductor, a second wire conductor securedto the thick portion ofthe Wall surrounding said circular opening, an insulator fixed upon saidinner electrode and having an opening for the passage of thefirst-mentioned wire conductor, a segmental conductor'mounted upon saidinsulator and to Which the first-mentioned Wire conductor is secured,and a tubularelectrode in which said segmental conductorsnugly fits.

4. In a device of the character described, an inner electrode having ashoulder, an outer electrode surrounding said inner electrode, a handlesecured to the inner electrode and abutting one end of said outerelectrode, a circular insulator having a peripheral groove and fittingupon the inner electrode at a point between the shoulder thereon andsaid handle, a conductor mounted in the groove of said insulator andfitting snugly within the outer conductor, and means threaded on theinner conductor for forcingthe outerconductor and. the circularinsulator firmly against the handle.

In testimony whereof I affix my signature.

WILLIAM M. MYERS.
